A liquid crystal display (LCD) including a LCD panel, a first polarizer and a second polarizer respectively disposed at two sides of the LCD, a first a-plate and a second a-plate disposed between the polarizers and LCD panel, a biaxial compensation plate and a c-plate is provided. The biaxial compensation plate is disposed between one of the polarizers and one of the a-plates. The main axis refractive indexes nx, ny and nz of the biaxial compensation plate satisfy the formula of Nz=(nx−nz)/(nx−ny), wherein nx>ny and −0.5<Nz<1. The first c-plate is disposed between one of the a-plates and LCD panel. The LCD of the present invention is capable of widening viewing angles and enhancing display quality.
